Mouse picks left of cursor

An issue just cropped up with my laptop: The mouse seems to be picking things an inch or tow to the left of the actual cursor. The cursor can move off the right side of the screen, too. So picking any horizontal trays on the right side of the screen is quite twitchy, as the cursor isn't visible.

The machine is an old Dell Lattitude D820 laptop. I went to Dell and downloaded drivers, but that didn't help. The game pops up a warning that my drivers are obsolete, both before and after I updated them.

A curiosity: The laptop identified its video card as a GeForce 7300 Go (?) before updating the drivers. After the update, it claims to have a NVIDIA Quadro NVS 110M.

Here's my CoH Helper log:

And as a reply to my own thread, if anybody cares:
It seems the problem goes away if I switch to Windowed Mode. No idea why it makes a difference.
